Geofabriform – New Technology for Tailings Dams
Geofabriform is a concrete-forming system that can be constructed quickly and easily. It can be used for slope protection, bank stabilization and port wharf construction. It is also durable and does not require additional time for heavy equipment to construct.
The seismic performance of a tailings dam with and without geofabriform is investigated through slope sliding test, direct shear test and unconfined compression test. The results show that the acceleration amplification factor and horizontal displacement of the dam with geofabriform are lower than those of the tailings dam without it.
It is a new technology for tailings dam construction
Geofabriform is a new technology that can be used to construct tailings dams. Its unique design allows for the formation of a continuous structure without using conventional cofferdams, making it safer and more environmentally friendly than traditional tailings dam construction. Moreover, it can be built in water and requires little maintenance. It is also suitable for other applications, including river, lake and sea dam slope protection, bank, wharf and port protection projects.
The performance of Geofabriform has been studied by means of slope sliding test, direct shear test and unconfined compression test. The results show that the shear strength of Geofabriform is a function of the geotextile material and tailings sand density, with a higher shear strength at lower sand density. The shear strength is also dependent on the fiber length, with longer fibers exhibiting better results.
In the slope sliding test, the tangent elastic modulus of the geofabriform increased gradually with increasing confining pressure, reaching a value of approximately 1800 kN per m3 at the shear stress level of 30 kPa. This result suggests that the sand-geotextile system can resist a large vertical load. Moreover, the tearing failure of the Geofabriform geotextile bag is hardly observed under the shear load. This is due to the fact that the geotextile is not pushed into the tailings and only the biting force between the fiber filament and the sand particles is exerted.
It is a new technology for tailings pond construction
Geofabriform is a new technology for the construction of tailings dams. It is a flexible, sustainable, and economical method that can save time and money in the construction of large-scale mining projects. It is also environmentally friendly and offers high safety levels. In addition, the permeability of the fabric allows process water to pass through and around the structure without affecting its stability. This is important, as the failure of a tailings dam can cause serious environmental and human damage.
In the construction of a geofabriform, a series of molds is positioned on the site to form a mold pattern. The resulting structure has a much stronger compressive strength and can withstand the lateral force applied to it. Moreover, the fabric is flexible and can withstand heavy mud deposits. Consequently, it can be used in various construction projects, including the construction of power plant ash disposal areas and mine metallurgy industry tailings ponds.
The BFRT consists of a number of split film yarn-woven geofabriforms hydraulically reclaimed with tailings. The geofabriforms are staggered in the length and width directions of a dam body. Each layer of the piled geofabriforms is interconnected with one another in a lap joint mode. This makes the BFRT aging resistant and has good anti-scouring safety performance. In addition, the BFRT is ideal for transformation and heightening of existing tailings dams. Moreover, the BFRT is highly effective in preventing the failure of tailings dams. In fact, the BFRT can be used as a replacement for conventional rockfill or soil-cement dams.

The full tailing hydraulic reclamation split film yarn woven geofabriform piled dam is geotextile manufacturer aging resistant and high in anti-scouring safety performance. It can be used to construct a power plant ash disposal area, mine metallurgy industry tailing pond, and so on. The advantages of this new technology are its low construction cost, high rising speed, and long service life. Moreover, the use of this technology can significantly increase the efficiency of mining and improve the environment.
TAILENG is a consortium of experts in the field of mining and power industry waste storage and recovery projects. Its goals are to develop fundamental and applied research to advance the state of practice in tailings design, operation, and closure. It also provides training and education to practitioners and students.
A new method for building fine-grained tailings dams has been developed. This method uses a series of geotextile tubes that are filled with a fine-grained, sandy sediment. The pipes are anchored by concrete or cement mortar to create a stable, long-lasting structure. The geotextile tube technology has been shown to have good seismic performance and is more efficient than traditional upstream tailings dam construction methods.
To ensure that tailings are properly managed, companies should establish a standard for public disclosure. This will help inform the public of potential environmental risks and mitigate the risk of disasters. A number of tools are available to help companies disclose information, including ArcGIS Hub, which allows them to easily build simple open data websites for public disclosure.
It is a new technology for tailings reservoir operation
The mold geofabriform method damming technology is a new and promising method for building fine-grained tailings dams. This new technology is characterized by high anti-scouring safety performance and can be built in rain weather, which improves construction efficiency. In addition, it is easy to maintain and is aging resistant. The mold geofabriform is also easy to use and has the same strength as a traditional anchored dike, making it an excellent choice for transformation, heightening and application of power plant ash disposal area, mine metallurgy industry tailing pond and other similar reservoir areas.
The friction and compressive properties of the geofabriform were investigated through slope sliding test, direct shear test, and unconfined compression tests. The results show that the consolidated geofabriform has a higher internal friction angle and cohesion than pure tailings sand. The ultimate compressive strength of the geofabriform reaches 28o and 40kPa under unconfined conditions.
Despite their essential role in the mining industry, the failure of tailings storage facilities can have devastating consequences for the mining firm and its surrounding communities. To prevent such disasters, the mining industry must invest in effective monitoring systems that can identify potential risks before a catastrophic failure occurs. These systems should be holistic and take a full-site approach to monitoring. For example, inclinometers can detect acoustic emission stress waves, which indicate slope displacement. These signals can be used in conjunction with other sensors, such as total earth pressure cells.
